Abstract

L'invention a trait à un procédé et à un appareil permettant de détecter des retards dans un réseau de communication. En général, des messages émanant de véhicules sont horodatés, et l'horodatage est comparé au temps de réception de chaque message par une station centrale. Un processeur situé au niveau de la station centrale détermine ensuite une différence de temps entre l'horodatage et le temps reçu. La différence de temps est ensuite comparée à un temps prédéterminé. Si le nombre de messages reçus par la station centrale au-delà du temps prédéterminé est supérieur à un nombre prédéterminé, un avis est envoyé à une entité, telle que le personnel de la station centrale.
